Adding EV Charger (100A) in Secondary Panel (100A) Fed Off Main (200A)

Introduction

As the world shifts towards electric vehicles (EVs), the need for efficient and reliable charging infrastructure is becoming increasingly important. Homeowners like you are looking for ways to charge their vehicles quickly and safely, but often face challenges with their existing electrical panels. In this article, we will discuss the process of adding an EV charger (100A) in a secondary panel (100A) that is fed off a main panel (200A).

Understanding Your Electrical Panel

Before we dive into the details, it's essential to understand your electrical panel setup. You have a main panel (200A) that feeds power to a secondary panel (100A). This secondary panel is where you plan to install your EV charger (100A). To maximize the charging speed of your Ford Charge Station Pro, you require 80A 240AC service. This is a significant amount of current, and you need to ensure that your electrical panel can handle it.

Assessing Your Electrical Panel's Capacity

To determine if your electrical panel can handle the additional load, you need to assess its capacity. The main panel (200A) is rated for 200 amps, which means it can handle a total load of 200 amps. The secondary panel (100A) is rated for 100 amps, which means it can handle a total load of 100 amps. Since you plan to install a 100A EV charger, you will need to ensure that the secondary panel can handle the additional load.

Calculating the Total Load

To calculate the total load, you need to consider the following factors:

  • The main panel's capacity (200A)
  • The secondary panel's capacity (100A)
  • The EV charger's rating (100A)
  • Any other loads connected to the secondary panel

Assuming you have no other loads connected to the secondary panel, the total load would be:

200A (main panel) + 100A (secondary panel) + 100A (EV charger) = 400A

However, since the secondary panel is rated for 100A, you will need to consider the panel's capacity and the EV charger's rating. In this case, the total load would be:

100A (secondary panel) + 100A (EV charger) = 200A

Upgrading Your Electrical Panel

If your electrical panel cannot handle the additional load, you may need to upgrade it. Upgrading your electrical panel involves installing a new panel that can handle the increased load. This may require hiring a licensed electrician to assess your electrical panel and determine the necessary upgrades.

Installing a New EV Charger

Once you have upgraded your electrical panel, you can install a new EV charger. When installing a new EV charger, it's essential to follow the manufacturer's instructions and local electrical codes. You will need to ensure that the charger is installed correctly and that it is compatible with your electrical panel.

Safety Considerations

When working with electrical panels and EV chargers, safety is paramount. You should always follow local electrical codes and safety guidelines to ensure that you and your family are protected from electrical shock and other hazards.

Conclusion

Adding an EV charger (100A) in a secondary panel (100A) fed off a main panel (200A) requires careful planning and consideration. You need to assess your electrical panel's capacity, calculate the total load, and determine if you need to upgrade your panel. Once you have upgraded your panel, you can install a new EV charger and follow local electrical codes and safety guidelines to ensure a safe and efficient charging experience.
